Their love-lives are in a near-state of constant flux following the end of their romance two years ago.

But despite Kourtney Kardashian having apparently struck up a new romance with Quincy Brown (P Diddy's son), her ex Scott Disick still carries a torch for the mother of his children.

Speaking to her younger sister Khloe in Sunday's episode of Keeping Up With The Kardashians, the 33-year-old entertainer and businessman admitted that he was "still turned on" by his ex, before he called her the love of his life.

In the latest instalment of E!'s long-running hit reality show, Scott is seen having a sit-down chat with Khloe, who can't help but grill him over his feelings for her elder sister.

Smiling as she leans in close to him, Khloe looks him straight in the eye as she asks about the current state of his love-life, probing: "Are you getting over Kourtney?"

As Scott tells her he isn't seeing anyone, she cheekily asks about the pair getting close during a holiday in Mexico last year, referring to him kissing Kourntey one night.

As they talk about what transpired, Scott admits: "I kissed her goodnight, but she didn't kiss me back."

Despit looking slightly sheepish when his ex came up, as Khloe pressed him about his feelings for her sister, he replied: "I'm still turned on by her if that's what you're asking."

Going back to Scott's relationship status, Khloe presses him on whether or not he's leaped into the dating game, with the bearded party-boy replying: "Uh-uh. I mean I technically could [date someone], but I don't feel comfortable doing that.

"I would never be over her, she's the love of my life. But, I've just tried everything i can to be there for her, and there's just no appreciation there.

Scott's party-loving lifestyle led to the collapse of his relationship with Kourtney and while he acknowledges he was largely to blame for their break-up, he is eager to see his family reunited.

Making another confession to the show's diary cam, the reality star adds: "You know I definitely realise that a lot of things are my fault. And I'm happy to take ownership of that, but I just hope some day that she realises that I don't want to be with anyone but her."

Scott and Kourtney have three children together: Mason, seven, Penelope four, and youngest son Reign, two.
